SCRAPER.

Application filed September 27, 1916.

To all whom t may concern Be it known that I, HANS l?. HnNsiiN, a citizen of the United States, residing at Tecumseh, in the county of Lenawee and State of Michigan, have invented certain new and useful Improvements in Scrapers, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in Scrapers and has relation more particularly to a device of this general character especially designed and adapted for use in connection with roadways; and it is an object of the invention to provide a novel and improved device including wings disposed on inclines in the same direction as the direction of travel of the device whereby the material loosened thereby is caused to be collected at the crown of the roadway.

It is also an object of the invention to provide a device of this general character wherein the wings are capable of adjustment relative to the width of the roadway J and whereby the same are supported for rocking movement in a vertical direction so said wings will readily conform to the surface of the road.

lThe invention also has for an object to provide a novel and improved device of this general character wherein a leveling member is disposed rearwardly of the convergent ends of the wings so that the material delivered to the crown of the road will be smoothed whereby the crown portion of the roadway will be conserved.

rIhe invention consists in the details of construction and in the combination and arrangement of the several parts of my improved scraper whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be denitely claimed.

In order that my invention may' be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure l is a view in perspective looking at the front of a scraper constructed in accordance with an embodiment of my invention; Fig. 2 is a view in perspective looking at the rear of my improved scraper as Speccation of Letters Patent.

herein embodied; F ig. 3 is a fragmentary v iew partly in elevation and partly in section illustrating the operative connection between the leveling member and the handles; and Fig. 4 is a fragmentary longitudinal sectional view taken through one of the wings and illustrating vcertain details of construction as herein disclosed.

As disclosed in the accompanying drawings, l denotes a draft pole of predetermined dimensions and with which the animals are adapted to be hitched in any desired manner.

2 2 denote arms secured to the opposite sides of the pole 1 at the rear thereof and disposed rearwardly from said pole l in diverging planes. Each of the arms 2 terminates in a depending extension 8 which is engaged by the clip 4 pivotally engaged, as at 5,' with a wing W preferably through the medium of a removable bolt. The bolt 5 also serves as a medium to retain in operative position the wear plate 6 overlying the outer face of the wing W and interposed between said wing and the clip 4. The plate @i is further maintained in applied position in any conventional manner but preferably through the medium of the removable bolt 7.

It will be at once self-evident that the coaction between the clip l and the extension 3 permits the wing W to swing in a vertical direction in order to readily conform to the surface of the roadway and also permits said wing to be swung in substantially a horizontal path so that the inclination of the same relative to the pole l may be readily regulated as will be controlled by the width of the roadway with which my improved scraper is employed.

The wing W is disposed on a forward ineline and is maintained against rearward movement through the medium of a ieXible member 8 herein disclosed as a linked chain anchored, as at 9, to the wing W intermediate the length thereof and adjustably engaged with a hook 10 carried by a side face of the pole l at a predetermined point in advance of the rear end thereof. rThe forward face of the wing lV has secured to the lower marginal portion thereof, and throughout its length, the metallic plate ll whereby a more effective contact will be had with the road surface. As the wings lV are disposed on forward and outward inclines, it will be carried to the center or crown of the roadway and the divergence of the arms 2 results in an exit opening between the inner ends of said wings through which said material will pass and be formed at the center or crown of the road substantially in the form of a ridge. In order that the width of the exit opening may be increased, I have found it of advantage to provide each of the wings W and plate 6 with a-supplemental opening 12 positioned inwardly of the bolt 5 as positioned in the accompanying drawings and through which said bolt is adapted to be disposed when the clip 4 is moved inwardly in order to increase the width of the exit opening as is believed to be clearly apparent to those skilled in the art to which my present invention appertains.

The rear face of each of the wings W is provided with the longitudinally spaced brackets 14 to afford a support for suitable weight whereby the proper contact of the wing with the road surface may be assured when the requirements of practice may so necessitate. Each of the wings `W adjacent its outer end is also provided with a hand hold 15 preferably secured to the upper edge thereof so that the wing may be readily adjusted in either a vertical or horizontal direction.

Secured to the rear end of the pole 1 and extending rearwardly and longitudinally thereof is a resilient arm or strap 16 which extends I.between the inner ends of the wings W and terminates a predetermined distance rearwardly thereof.

17 denotes a leveling member of a width materially in excess of the space between the inner ends of the wings W and which is arranged perpendicular to the pole 1 and is adapted to coact with the crown of the roadway and serves to smooth or level the material discharged between the inner ends of the wings W through the exit opening afforded by the space therebetween, whereby it will be perceived that as the scraper passes over the roadway the surface will be left in a finished condition. The leveling member 17 midway its length is provided with the bracket 18 to which the rear extremity of the arm or strap 16 is secured and to which is also secured the lower extremities of the controlling handles 19, said handles 19 being of a well known type and for a purpose which is believed to be selfevident.

In the event a road surface should have a plurality of stones or other obstructions thereon, it will be at once self-evident that with my improved scraper the same may be forced to the center or crown of the roadway and very easily and conveniently collected. It lwill also be understood that when my device is employed for this purpose the leveling member 17 is removed.

F rom the foregoing description, it is thought to be obvious that a scraper constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as hereinafter claimed.

1. A device of the character described comprising, in combination, a draft pole, diverging arms secured to the rear portion of said pole, each of said arms terminating in a depending extension, a wing, and a clip pivotally engaged with the inner end portion of said wing and movablel on a horizontal axis, said clip coacting with the extension of an arm for pivotally connecting the wing thereto for movement in a horizontal direction.

2. A device of the' character described comprising, in combination, a draft pole, forwardly and outwardly inclined wings positioned at opposite sides of the draft pole and connected thereto, the inner ends of said wings being spaced apart to afford an exit opening, a resilient arm secured to the draft pole and extending rearwardly therefrom and terminating rearwardly of the inner ends of the wings, a leveling member disposed transversely of the pole and secured to the outer end of the arm, and an upstanding handle member carried by the leveling member.

In testimony whereof I hereunto aihx my signature in the presence of two witnesses.k
